These Terms of Use ("Terms") form a legally binding agreement between you ("you" or "your") and GainLogger ("we," "us," or "our") and govern your access to and use of the GainLogger mobile application, Apple Watch companion app, website, and related services (collectively, the "Services"). By downloading, installing, accessing, or using the Services, or by checking a box or tapping a button indicating your acceptance, you acknowledge that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference. If you do not agree to these Terms, do not use the Services.
Please read these Terms carefully. They include a release and assumption of risk for physical activity (Section 5), disclaimers of warranties (Section 13), a limitation of our liability (Section 14), your obligation to indemnify us (Section 15), and a binding individual arbitration agreement and class-action waiver (Section 16) that affect your legal rights. Exercise carries an inherent risk of serious injury or death — you participate at your own risk.
You must be at least 16 years old to use the Services. By using the Services, you represent and warrant that you are at least 16 years of age and have the legal capacity to enter into these Terms.
If you are between 16 and 18 years of age (or the age of legal majority in your jurisdiction), you may use the Services only with the involvement, consent, and supervision of a parent or legal guardian who agrees to be bound by these Terms on your behalf and accepts responsibility for your use of the Services and for any physical activity you undertake. By using the Services, you represent that such consent has been obtained. We do not knowingly permit use by anyone under 16. See Section 9 of our Privacy Policy regarding minors.
To use the Services, you must create an account using an email address or a supported social login provider (Google or Apple). You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account, whether or not authorized by you. You agree to provide accurate, current, and complete information and to keep it up to date. You must notify us immediately at support@gainlogger.app of any unauthorized use of your account or any other breach of security. We are not liable for any loss or damage arising from your failure to safeguard your credentials.
GainLogger is a fitness tracking application that allows you to log workouts, track exercises, create workout templates, monitor personal records, view your fitness progress, and receive automated, algorithmically generated progression suggestions. The Services include a mobile app, an Apple Watch companion app, and a website. The Services are provided for your personal, non-commercial use only, and are licensed, not sold, to you on a limited, revocable, non-exclusive, non-transferable basis.
The GainLogger Apple Watch companion app allows you to start and control workout sessions, log sets, and view rest timers directly from your wrist. With your permission, the Watch app reads heart rate and active energy data from Apple HealthKit to enrich your workout sessions with training-intensity metrics. You may grant or revoke HealthKit permissions at any time in your device's Settings. The Watch app can operate independently when your iPhone is not nearby by caching templates and using a stored authentication token. Heart rate, calorie, and other metrics displayed are estimates, may be inaccurate, and must not be relied upon for any medical or safety-critical purpose.
You may not use the Services for any unlawful purpose or in any way that could damage, disable, overburden, or impair the Services.
GainLogger is not a medical device, healthcare provider, or medical-advice service, and does not provide medical advice, diagnosis, or treatment.
The workouts, templates, exercises, progression suggestions, analytics, heart-rate and calorie estimates, and all other content and information made available through the Services (including data sourced from Apple HealthKit and content shared by other users) are provided for general informational and self-tracking purposes only. They are generated automatically based on data you enter and generic rules; they are not personalized medical, healthcare, nutritional, or professional fitness advice and are not a substitute for consultation with a qualified physician, licensed healthcare provider, or certified fitness professional.
You should consult a physician before beginning any exercise program, especially if you are pregnant, elderly, have any pre-existing medical condition, injury, or disability, or have any concern about your fitness to exercise. We strongly recommend completing a pre-participation health screening (such as a PAR-Q) with a qualified professional. Never disregard professional medical advice or delay seeking it because of anything you have read or accessed through the Services. If you experience pain, dizziness, shortness of breath, chest discomfort, or any other symptom, stop exercising immediately and seek medical attention. In a medical emergency, call your local emergency number.
You are solely responsible for selecting exercises, weights, intensities, and volumes appropriate to your own ability, for using correct form and equipment, for warming up and progressing safely, and for exercising within your personal limits.
You understand and acknowledge that physical exercise, strength training, and other physical activities are inherently dangerous and carry a risk of serious bodily injury, illness, aggravation of pre-existing conditions, disability, or death, as well as property damage. These risks may arise from your own actions or inactions, the actions or inactions of others, equipment, the condition of the premises where you exercise, your physical condition, or your use of (or reliance on) the Services, including any workout, template, progression suggestion, or metric.
You voluntarily and knowingly assume all such risks, whether known or unknown, and accept full and sole responsibility for your participation in any physical activity undertaken in connection with the Services.
To the maximum extent permitted by applicable law, you hereby release, waive, discharge, and covenant not to sue GainLogger and its owners, officers, employees, agents, licensors, and suppliers (the "Released Parties") from and against any and all claims, demands, liabilities, costs, and causes of action of any kind — including those based on negligence — arising out of or relating to any injury, death, loss, or damage you suffer in connection with your use of, or reliance on, the Services or any physical activity undertaken in connection with the Services.
This release does not apply to liability that cannot be excluded or limited under applicable mandatory law (for example, liability for death or personal injury caused by our gross negligence or willful misconduct, or for fraud). If you are a consumer, this Section applies only to the extent permitted by the consumer-protection laws of your country of residence, and does not affect your mandatory statutory rights.
We make no representation, warranty, or guarantee that using the Services will produce any particular fitness, health, strength, weight, body-composition, performance, or other result. Individual results depend on many factors outside our control, including your effort, genetics, nutrition, rest, technique, and adherence. Any examples, suggestions, or progression recommendations are illustrative only and are not a promise of outcomes.
GainLogger offers a free tier with limited features and a paid subscription ("GainLogger Pro") that unlocks additional functionality.
You retain ownership of all content you create or upload through the Services, including workout data, exercise photos, workout templates, and health metrics collected from Apple HealthKit ("User Content"). You grant us a worldwide, non-exclusive, royalty-free license to host, store, reproduce, process, and display your User Content solely to operate and provide the Services to you and, where you choose to share content, to the users you share it with.
You are solely responsible for your User Content and represent that you have all rights necessary to submit it and that it does not infringe or violate the rights of any third party or any law.
The Services may allow you to share workout templates and to view, download, or use templates and other content created and shared by other users ("Third-Party Content"). Third-Party Content is created by users, not by us. We do not author, endorse, verify, or guarantee the safety, accuracy, suitability, or legality of any Third-Party Content, including any shared workout, exercise selection, weight, or progression. You use Third-Party Content entirely at your own risk, and Sections 4, 5, 6, 13, and 14 apply fully to it. If you use social features such as template sharing or user search, your display name and public ID may be visible to other users; your email address is never exposed to other users.
If you believe content available through the Services infringes your intellectual property or other rights, contact us at support@gainlogger.app and we will respond as required by applicable law.
The Services, including all software, designs, text, graphics, trademarks, logos, and other content (excluding User Content and Third-Party Content), are owned by GainLogger or its licensors and are protected by applicable intellectual property laws. We grant you a limited, revocable, non-exclusive, non-transferable license to use the Services for their intended purpose. You may not copy, modify, distribute, sell, lease, sublicense, create derivative works from, reverse engineer, or otherwise exploit any part of the Services without our prior written consent, except to the extent such restriction is prohibited by applicable law.
You agree not to:
By creating an account, you consent to receive transactional and service communications from us electronically — including email verification codes, password-reset and security notices, account and subscription notices, and changes to these Terms or our Privacy Policy. These communications are a necessary part of the Services and cannot be opted out of while you maintain an account.
We will send you marketing and promotional communications (such as feature announcements, tips, and news) only if you opt in. You may withdraw your marketing consent at any time, free of charge, by toggling the marketing-emails setting in the app (Settings → Privacy) or by using the unsubscribe link included in any marketing email. Withdrawing marketing consent does not affect transactional communications. You agree that all agreements, notices, disclosures, and other communications we provide electronically satisfy any legal requirement that they be in writing.
You may delete your account at any time from the Account tab in the app. Upon deletion, your data will be permanently removed from our systems as described in our Privacy Policy.
We may suspend or terminate your access to the Services at any time, with or without notice, if you violate these Terms, if required by law, or if we reasonably believe your conduct is harmful to other users, third parties, or the Services. Upon termination, your license to use the Services ends immediately. Sections that by their nature should survive termination — including Sections 4, 5, 6, 8, 9, 13, 14, 15, 16, 17, and 19 — will survive.
To the maximum extent permitted by applicable law, the Services and all content are provided "as is" and "as available," with all faults and without warranties of any kind, whether express, implied, statutory, or otherwise. We expressly disclaim all implied warranties, including warranties of merchantability, fitness for a particular purpose, title, accuracy, and non-infringement.
We do not warrant that the Services will be uninterrupted, timely, secure, error-free, or free of viruses or other harmful components, that defects will be corrected, that any data (including workout history) will be preserved or accurate, or that the Services will meet your requirements or produce any particular result. Any material obtained through the Services is accessed at your own discretion and risk.
Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you. Where required, your mandatory statutory consumer rights remain unaffected.
To the maximum extent permitted by applicable law, in no event will the Released Parties be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenues, data, use, goodwill, or other intangible losses, or for any personal injury or death (except as cannot be excluded by law), arising out of or relating to your use of, or inability to use, the Services, your reliance on any content, any Third-Party Content, or any physical activity undertaken in connection with the Services — whether based on warranty, contract, tort (including negligence), statute, or any other legal theory, and whether or not we have been advised of the possibility of such damages.
To the maximum extent permitted by applicable law, the total aggregate liability of the Released Parties for all claims arising out of or relating to the Services or these Terms will not exceed the greater of (a) the total amounts you paid to us for the Services in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) USD $100.
These limitations are a fundamental basis of the bargain between you and us and apply even if a limited remedy fails of its essential purpose. Nothing in these Terms excludes or limits our liability where it would be unlawful to do so — including, where applicable, liability for death or personal injury caused by our gross negligence or willful misconduct, for fraud or fraudulent misrepresentation, or for any liability that cannot be excluded under the mandatory consumer-protection law of your country of residence. If you are a consumer, these limitations apply only to the extent permitted by such mandatory law, and your statutory rights are unaffected.
To the maximum extent permitted by applicable law, you agree to defend, indemnify, and hold harmless the Released Parties from and against any and all claims, demands, actions, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising out of or relating to: (a) your use or misuse of the Services; (b) your User Content; (c) your violation of these Terms or of any applicable law or regulation; (d) your violation of the rights of any third party; or (e) any injury, death, loss, or damage suffered by you or any third party in connection with any physical activity you undertake in connection with the Services. We reserve the right, at our own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you, in which case you will cooperate with us. This Section does not apply to the extent the relevant claim arises from our own gross negligence or willful misconduct, or where indemnification by a consumer is prohibited by mandatory law.
Please read this Section carefully — it affects how disputes are resolved and limits the ways you can seek relief.
Before starting any formal proceeding, you agree to first try to resolve the dispute informally by emailing us at support@gainlogger.app with a description of the dispute and the relief you seek. We will attempt in good faith to resolve it. If we cannot resolve the dispute within sixty (60) days, either party may proceed as set out below.
Except as set out in the carve-outs below, any dispute, claim, or controversy arising out of or relating to the Services or these Terms that is not resolved informally will be finally settled by binding arbitration on an individual basis, conducted in Israel and seated in Israel under the Israeli Arbitration Law, 5728-1968, by a single arbitrator. The language of the arbitration will be English or Hebrew. Judgment on the award may be entered in any court of competent jurisdiction. You and we each waive the right to a trial by jury where applicable.
To the maximum extent permitted by applicable law, you and we agree that each may bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, or representative proceeding. The arbitrator may not consolidate more than one person's claims or preside over any form of class or representative proceeding.
You may opt out of this arbitration agreement and the class-action waiver by emailing support@gainlogger.app within thirty (30) days of first accepting these Terms, stating your name, account email, and that you opt out of arbitration. Opting out will not affect any other part of these Terms.
These Terms and any dispute arising out of or relating to them or the Services are governed by the laws of the State of Israel, without regard to its conflict-of-law rules, and the United Nations Convention on Contracts for the International Sale of Goods does not apply. Subject to Section 16 (Arbitration), the competent courts located in Tel Aviv-Jaffa, Israel will have exclusive jurisdiction, and you consent to their jurisdiction and venue. If you are a consumer, nothing in this Section deprives you of the protection of the mandatory consumer-protection laws of your country of residence, and you may also be entitled to bring proceedings in the courts of that country.
We may update these Terms from time to time. The updated version will be indicated by the "Last updated" date at the top of this page. If we make material changes, we will notify you through the app or by email and, where required, ask you to re-accept the updated Terms before continuing to use the Services. Your continued use of the Services after changes take effect constitutes your acceptance of the updated Terms. If you do not agree to the updated Terms, you must stop using the Services and may delete your account.
